Create and manage VPC

The VPC (Virtual Private Cloud) in KakaoCloud is a user-defined private network service. By using a VPC, users can combine multiple network components to quickly and easily build a network suited to their environment.
The following describes how to create and manage a VPC in the VPC service.

Permission notice

• VPC role management follows IAM role-based access control (RBAC), and only Project Admin can create and manage VPCs. Project members can only view VPCs.
  
• You can check your role in KakaoCloud console > Profile (top right) > Organization role or Project role.

Create VPC

You can create a new VPC.

info

You can create up to three VPCs per project.

1. Go to KakaoCloud console > Networking > VPC.

2. In the VPC menu, click the [Create VPC] button.

3. Enter the required information to create a VPC, and then click the [Create] button.

   Create VPC

   Category	Description
   ⓵ VPC information	- Name: Enter the VPC name - IP CIDR block: Enter the VPC IP CIDR block ㄴ You can create it by entering a range from the private IP ranges (172.16.0.0 / 192.168.0.0 / 10.0.0.0) ㄴ Prefix length: Select between 16–24
   ⓶ Subnet settings	Check subnet information - Number of subnets per availability zone: One is set by default and can only be selected within the quota ㄴ Public type: One is set by default and can only be selected within the quota ㄴ Private type: Select from 0–10, within the quota - Subnet CIDR block: Displayed according to the number of configured public and private subnets ㄴ For the Private type, the prefix length can be selected between 20–26
   ⓷ Topology	You can preview the configuration graph that changes according to the VPC information, availability zone, and subnet settings

View VPC list and basic information

View the list of currently created VPCs and their basic information.

1. Go to KakaoCloud console > Networking > VPC.

2. Click the VPC menu, and then check the list of currently created VPCs and their basic information.

   Category	Description
   Name	Name of the VPC
   ID	Unique ID of the VPC
   Status	Status of the VPC - Active: Activated - Pending Create: Creating - Pending Update: Updating - Pending Delete: Deleting - Error: Error occurred
   IP CIDR block	IP CIDR block of the VPC
   Created at	Date and time when the VPC was created

   info

   After creating a VPC, even when the status becomes Active, it may take up to about 20 minutes for internal VPC components such as the DNS resolver to complete configuration.

Rename VPC

You can change the name of a VPC.

1. Go to KakaoCloud console > Networking > VPC.
2. Click the VPC menu, and then select [⋮] > Rename for the VPC whose name you want to change.
3. Enter the information in the pop-up window, and then click the [Save] button.

Configure DNS resolver query logging

You can configure query logging for the DNS resolver in a VPC.

Enable DNS resolver query logging

To enable DNS resolver query logging for a specified VPC, you must first prepare an Object Storage bucket to store log files and an S3 access key required for the authentication process to store the files.
Refer to DNS resolver query logging and create each resource in advance.

The following describes how to enable DNS resolver query logging.

DNS resolver query logging configuration

1. Go to KakaoCloud console > Networking > VPC.
2. Click the VPC menu, and then select [⋮] > Configure DNS resolver query logging for the VPC where you want to enable DNS resolver query logging.
3. Change the status from Disabled to Enabled.
4. In Select bucket, choose the Object Storage bucket where the log files will be stored and select the S3 access key.
   • You can enable encryption for the bucket. For security reasons, encrypting the bucket is recommended. For more information about creating an Object Storage bucket, see Object Storage > Create and manage buckets.
5. Click the [Save] button.

info

• If the Object Storage bucket specified as the storage destination in DNS resolver query logging is deleted, query logs will not be stored normally. If the bucket is deleted, configure the settings again and specify another bucket.
• If the account permissions change while DNS resolver query logging is enabled, query logs may not be stored normally. Reconfigure the permissions for the account that set up DNS resolver query logging so that it can configure query logs.
• For VPCs created before the feature release on June 12, 2025, a migration process will be performed in stages to enable this feature. For related inquiries, contact the Helpdesk.

Disable DNS resolver query logging

The following describes how to disable DNS resolver query logging.

1. Go to KakaoCloud console > Networking > VPC.
2. Click the VPC menu, and then select [⋮] > Configure DNS resolver query logging for the target VPC.
3. Change DNS resolver query logging configuration to [Disabled].
4. Click the [Save] button.

Delete VPC

You can delete a VPC.

1. Go to KakaoCloud console > Networking > VPC.
2. Click the VPC menu, and then select [⋮] > Delete for the VPC you want to delete.
3. Enter the required information, and then click the [Delete] button.
